ASSIGNOR TO FRIED. KRUPP, AKTIENGESELLSCHAFT, OF ESSEN-ON- TIME-FUSE.

SPECIFICATION forming part of Letters Patent No. 776,100, dated November 29, 1904.

Application filed October 2, 1903.

To all whom it may concern:

Be it known that I, KARL WVInsER, a subject of the Emperor of Germany, and a resident of 34 Friederikenstrasse, Riittenscheid, near Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Time- Fuses, of which the following is a specification.

The present invention relates to time-fuses in which the setting-piece may readily be turned by hand, and has for its object to secure the time adjustments of a fuse in firing. For this purpose, according to the present invention, one of the two relatively adjustable parts of a fuse is provided with a bolt of hard material movable in the direction of the axis of the fuse, while the other is provided with an annular lip projecting into the path of the bolt or into the path of a portion of its section, so that, upon firing, the bolt, in consequence of its inertia, will cut out a portion of the annular lip and enter the out thus formed, so as to prevent relative turning between the parts thereafter.

One embodiment of the present invention is shown, by way of example, in the accompanying drawings, in which- Figures 1 and 2 are longitudinal sections through a fuse, showing the relative positions of the parts before and after firing, respectively. Fig. 3 is a section of a fuse on the line 3 3 of Fig. 1 looking from above. Fig. 4c is a section through the setting-ring.

The general arrangement of the fuse is known, and it will be only necessary to describe the parts which are immediately concerned in the present invention.

Over the fuse-body A is placed the setting ring D, and upon the upper portion of the fuse-body is screwed the closing-cap 0. The setting-ring D, which has an annular extension (Z projecting into a groove of the fusebase F, is provided with a comparatively thin annular lip cl. In the fuse-body A and parallel to the longitudinal axis of the fuse is arranged a groove a, the section of which is in part cylindrical and part angular. The cylindrical part of the groove (0 is formed with incisions in its Wall which may be of any suitable kind. In the fuse illustrated in the draw- Serial No. 175,487. (No model.)

ings these incisions are formed by a screwthread. In the angular portion of the groove a is located a bolt J, constructed of steel or other hard material, the section of which corresponds to that of the groove. A portion 71 of the bolt J projects beyond the cylindrical rim of the fuse-body, as'shown more clearly in Fig. 3. This projecting portion 2' of the bolt rests upon the annular lip d before firing. Fitting loosely above the bolt J in the cylindrical portion of the groove a is a correspondingly formed body L of soft and heavy material, such as lead.

When the shot is fired, the bolt J is held back by its inertia and remaining back cuts out a portion of the annular lip (Z, and enters the recess thus formed with its projection 11. By this means the setting-ring will be locked in its previously-adjusted position, so that it cannot be moved from its adjustment by the rotation of the projectile during its flight.

The leaden body L increases the cutting force of the bolt J. In addition to this function it serves to hold. the bolt in its locking position, since it will be spread out by the impact of the bolt J against the base of its guiding-groove and securely clamped against the Walls of the groove. -The security of this clamping is materially increased by the incisions already-referred to in the upper portion of the groove (0 and into which the leaden body is pressed.

Having thus described the invention, the following is what is claimed as new therein:

1. In a time-fuse, means for securing the relatively adjustable parts at the time of firing consisting of a bolt movable under its inertia on one of said parts in the direction of the axis of the fuse and metal softer than said bolt on the other of said parts out into by the bolt at the time of firing, to prevent relative adjustment.

2. In a time-fuse, means for securing the relatively adjustable parts at the time of firing consisting of a bolt movable under its inertia on one of said parts in the direction of the axis of the fuse, metal softer than said bolt on the other of said parts out into by the bolt at the time of firing, to prevent relative adjustment, and means for holding the bolt against movement after it has moved under its inertia.

3. In a time-fuse, means for securing the relatively adjustable parts at the time of firing consisting of a bolt movable under its inertia on one of said parts in the direction of the axis of the fuse, metal softer than said bolt on the other of said parts out into by the bolt at the time of firing, to prevent relative adjustment, and soft metal movable to spread and hold the bolt against movement after said bolt has moved under its inertia.

eL. In a time-fuse, means for securing the relatively adjustable parts at the time of firing consisting of a bolt made of hard material and movable under its inertia on one of said parts in the direction of the axis of the fuse and an annular lip made of soft material carried by the other of said parts and cut by said bolt or a portion thereof at the time of firing, to prevent relative adjustment.

5. In a time-fuse, means for securing the setting-ring against relative movement on the body of the fuse at the time of firing, comprising an annular lip projecting from one of said parts and a bolt mounted on the other of said parts, movable relatively thereto by its oWn inertia in the direction of the axis of the fuse, at time of firing and having a projection Which overhangs the annular lip prior to firing and cuts through said lip and remains in the 1recess formed therein, when the shot is firec.

6. In a time-fuse, means for securing the setting-ring against relative movement on the body of the fuse at the time of firing, comprising an annular lip projecting from one of said parts, a bolt mounted on the other of said parts, movable relatively thereto by its own inertia in the direction of the axis of the fuse, at time of firing and having a projection which overhangs the annular lip prior to firing and cuts through said lip and remains in the recess formed therein, When the shot is fired and a body of soft and heavy material located above the bolt to increase the cutting force of the latter.

7 In a time-fuse, means for securing the setting-ring against relative movement on the body of the fuse at the time of firing, comprising an annular lip projecting from one of said parts, a bolt mounted on the other of said parts, movable relatively thereto by its oWn inertia in the direction of the axis of the fuse, at time of firing and having a projection Which overhangs the annular lip prior to firing and cuts through said lip and remains in the recess formed therein, When the shot is fired and a body of soft and heavy material located above the bolt to increase the cutting force of the latter, movable in a groove and Wedging therein under the impact of the bolt.

8. In a time-fuse, means for securing the setting-ring against relative movement on the body of the fuse at the time of firing, comprising an annular lip projecting from one of said parts, a bolt mounted on the other of said parts, movable relatively thereto by its oWn inertia in the direction of the axis of the fuse at time of firing, and having a projection which overhangs the annular lip prior to firing and cuts through said lip and remains in the recess formed therein when the shot is fired, and a body of soft and heavy material located above the bolt to increase the cutting force of the latter movable in a groove and wedging therein under the impact of the bolt; said groove being provided with incisions to increase the holding efiect of the body wedged therein.

The foregoing specification signed at Dusseldorf this 17th day of September, 1903.
